Title: Improvements in or relating to automatic regulators
Filed: 1935-09-25
Abstract: 463,549. Fluid-pressure servomotorcontrol systems. ELECTROFLO METERS CO., Ltd. (Dunglinson, B.) Sept. 25, 1935, No. 26552. [Class 135] A regulating-apparatus for controlling the condition, pressure, or flow of a fluid comprises a normally balanced lever 32 on a fixed pivot 34 which is adapted to be unbalanced by a change in the condition of the fluid to be controlled, for example, the flow of fluid in a conduit 12 which produces a change in the pressures on the two sides of a diaphragm 22. The resulting movement of the lever 32 controls the escape through a jet pipe 52 of a pressure fluid acting on a diaphragm 56 against a counter-weight 102. The diaphragm 56 acts as an amplifying device for the change in the physical condition of the controlled fluid and actuates a pilot valve 70 through a lever 84 to supply fluid pressure to one side or the other of a power piston 78 for effecting an adjustment of the regulator setting, in this case a valve 10 in the conduit 12. The lever 84 is also connected to the power piston 78 to provide a follow-up to restore the pilot valve 70 to its neutral position. Between the amplifying diaphragm 56 and the normally balanced lever 32 is a dashpot and spring device 86, 90, 92 to provide a restoring movement of the lever 32 in advance of the return to normal of the flow in conduit 12 to prevent hunting. This is effected by the tensioning of the spring 92, on movement of the dashpot 86 connected to the diaphragm 56, which tension gradually fades out by acting on the piston 90 of the dashpot as the condition of the fluid in conduit 12 returns to normal.

Abstract: 679,329. Rotary engine and compressors. UNGEMACH, H. Oct. 31, 1950 [Oct. 31, 1949], No. 26605/50. Class 110(ii) An outwardly-sliding vane engine or compressor has a rotor built up of members 5 having spring-pressed packing pieces 9 bearing against casing ends 15 and against the sides 21 of vanes 16. The members 5 are suppported by pins 6 in a rotor 7 on a shaft 4. Each vane 16 is provided with trunnions 33 bearing on cams 35 the trunnions being surrounded by resilient bands or links 38. Pins 20 support pairs of plates 21 at each side of a vane, a slot 22, Fig. 9 (not shown) between each pair allowing the plates to pivot slightly on their pins. Annular grooves 23, in each pair of plates, contain spring rings 24 which press the plates against ends 15. A spacing ring 25 holds the pairs of plates 21 parallel. Packings 26, 27, each shaped as a half suare, are pressed outwards by spring rings 29, so that three sealing surfaces 31 are pressed against the ends 15 and the casing box 18. The ring 25 supports the lower halves of plates 26, 27 and transmits centrifugal force from the plates, through the rings 24 to the two outer plates 21 and from them to the trunnions 33. Figs. 1, 2 show an internalcombustion engine with inlet and exhaust ports 40, 41 and a socket 42 for a sparking plug (unless compression-ignition is used). Combustion spaces 43 and a cooling jacket 39 are provided. The rotor may be arranged eccentrically in a casing which then provides one crescent-shaped working- chamber. The engine may be modified to act as a pump or compressor or be used with liquid as working-fluid. The packing pieces 9 may have their separating spaces staggered, from one groove to the next. In Fig. 3 (not shown) the inlet and exhaust ports are duplicated.

Title: Improvements in or relating to devices for controlling the tension of paper, textile fabrics, or other flexible material during winding or unwinding
IPC: B65H23/06
Filed: 1930-09-11
Abstract: 369,239. Brakes. BETHLEHEM STEEL CO., Bethlehem, Pennsylvania, U.S.A.-(Assignees of Nieman, H. W. ; 115, East Market Street, Bethlehem, Pennsylvania, U.S.A.) Sept. 11, 1930, No. 27203. Convention date, Sept. 12, 1929. [Class ‹103 (i).] In apparatus for unwinding paper, textile fabrics, or other flexible material from a drum at constant tension, the rotation of the drum is controlled by a friction element engaging a cylindrical surface and acted upon at one end - by a force tangential to the cylindrical surface and opposed to the direction of rotation thereof, the wrap or angle of engagement of the friction element being sufficiently great that its torque is independent of the coefficient of friction, and the force applied to the friction element is automatically controlled by a member moving in accordance with the varying diameter of the material on the drum. In the device shown in Figs. 1 and 2, a cylindrical member 13 secured to the shaft of the unwinding roll 11 is engaged by a flexible friction element comprising a band 24 attached at one end to a link 37 and connected at the other end to a pin 30 spanning the adjacent ends of a pair of spaced outer bands 23, the other ends of which are connected to a link 29 pivoted to the end of a lever 43 acted upon by a tension spring 16. The bands 23, 24 comprise steel strips having facings.of friction material and together make more than a complete turn round the cylinder 13. Owing to the large angle of wrap and the fact that the spring 16 applies a tangential force to the friction element opposed to the rotation of the roll the torque exerted by the bands is independent of variations in the coefficient of friction. The link 37 is connected to an arm 39 fixed to a shaft 40 to which is also secured an arm 41 carrying a roller 17 held in constant engagement with the roll 11 by a spring 42. As the diameter of the roll decreases the link 37 rises, allowing circumferential movement of the bands 23, 24 and a gradual diminution of the tension of the spring 16 and thus of the braking action on the roll. One end of the spring 16 is attached to a block 46 adjustable on an arcuate guide 47 to enable the normal tension of the material to be varied.

[Class 80 (ii)] In a constant velocityratio universal joint of the kind in which balls, 22, or rollers lie in curved intersecting grooves 18 in the opposed faces of interengaging axial claws 14 of shaft members 10, 12, and transmit drive therebetween, but do not of themselves prevent axial separation of the members, such separation is prevented by a central ball 28, which is turned to a locking position in which it prevents the driving balls 22 from moving radially inwards sufficiently to allow separation of the members 10, 12. In assembly, three of the four driving balls 22 can be introduced into their grooves past the central ball 28, whilst the fourth is allowed to pass through a cutaway part 30 of the central ball. The latter is then turned to move the cut-away part out of registry with the driving ball and is locked by a pin 32, retained in a boring in the central ball by a transverse screw 38.

Abstract: 1276086 Glass helices DEFENCE SECRETARY OF STATE FOR 10 June 1969 [10 June 1968] 27397/68 Heading C1M A helix 11 or flat spiral 12 of glass or silica tubing, is produced by attaching the tubing 13 to a rotatable chuck 19, softening tube 13 by heating (e.g. by gas burners or electric heaters at 22), gauging the softness of the tube, and rotating the chuck 19 to an extent controlled by said softness, whereby the chuck causes the tube to move past the softening means and the tube is shaped without contacting any member where the tube is hot. In one embodiment (Fig. 3) the chuck 19 is driven by motor 27 via a constanttorque clutch 33, so that the chuck 19 rotates only if the tube is sufficiently soft. The clutch slips if the tube is too stiff. Tachometer 37, which records the chuck rotation, controls a servo 38 which operates the lead screw 40, so that relative motion is imparted to the glass support means 42. If, as in Fig. 3, the relative motion is along the chuck axis a helix is obtained. Alternatively the relative motion may be perpendicular to the chuck axis (Fig. 4), in which case a flat spiral 12 is obtained. In this embodiment a constanttorque may also be used, rotation of chuck 19 controlling lead screws 40a, 40b via servos 38a, 38b. Instead of a constant-torque clutch the glass softness may be gauged simply by a temperature-sensing device, e.g. an infra-red pyrometer, such that chuck 19 rotates only when the tube is at a predetermined temperature. Air, preferably under pressure, may be introduced into the tubing. By combining the relative motions used in the two embodiments more complex shapes can be achieved, e.g. a conical helix.
